PURPOSE OF REVIEW: Percutaneous nephrolithotomy (PCNL) continues as the gold standard for the surgical management of large renal stones. This short review is intended to highlight recent publications on PCNL of all tract sizes, from mini to standard. RECENT FINDINGS: Literature on PCNL in the last 2 years has focused on several main themes - decreasing complications, improving postoperative pain control, and new technology to improve outcomes. Mini-PCNL continues to prove effective and safe, with a new vacuum sheath showing promise of improving stone-free rates and decreasing infections...

PURPOSE OF REVIEW: There is a growing interest in nonantibiotic prevention strategies for recurrent urinary tract infections (rUTIs). Our objective is to provide a focused, pragmatic review of the latest evidence. RECENT FINDINGS: Vaginal estrogen is well tolerated and effective for preventing rUTI in postmenopausal women. Cranberry supplements at sufficient doses are effective in preventing uncomplicated rUTI. Methenamine, d-mannose, and increased hydration all have evidence to support their use, although the evidence is of somewhat variable quality...

PURPOSE OF REVIEW: Prostate biopsy is commonly performed in men suspected to have prostate cancer. It has traditionally been performed using a transrectal approach, but transperineal prostate biopsy has been increasingly adopted in part because of its lower associated infectious risk. We review recent studies evaluating the rate of potentially life-threatening post-biopsy sepsis and potential preventive strategies. RECENT FINDINGS: After performing a comprehensive literature search, 926 records were screened and 17 studies published in 2021 or 2022 were found to be relevant...

PURPOSE OF REVIEW: To give an overview of the most relevant recent literature about urinary tract infections (UTI) after radical cystectomy and to discuss them in the context of new individualized therapy approaches and possible preventive measures. RECENT FINDINGS: UTI following radical cystectomy is a common complication associated with significant morbidity and readmission risk. Recent literature focuses on the identification of risk factors and the optimization of management...

PURPOSE OF REVIEW: Male infertility may be secondary to male genital tract infection (MGTI) in an estimated 15% of cases. In the absence of overt clinical signs, evaluation for MGTI beyond semen analysis is not well established. Therefore, we review the literature on the evaluation and management of MGTI in the setting of male infertility. RECENT FINDINGS: A set of international guidelines recommends semen culture and PCR testing, but the significance of positive results remains unclear...

PURPOSE OF REVIEW: Caliceal diverticula are relatively uncommon within urologic practice and may be difficult to diagnose and treat. We aim to highlight contemporary studies examining surgical interventions for patients with caliceal diverticula, with a focus on percutaneous intervention, and provide updated practical recommendations for the management of these patients. RECENT FINDINGS: Studies within the last 3 years examining surgical treatment options for caliceal diverticular calculi are limited...

PURPOSE OF REVIEW: Recently, several trials as well as registry-data analyses investigating the role of robot-assisted radical cystectomy with extra or intracorporal urinary diversion were completed and follow up matured. This review aims to comment on the current evidence-based findings and interpret the future role of the robotic approach as a part of the treatment of bladder cancer. RECENT FINDINGS: Numerous trials and registry-data analyses revealed no significant differences in progression-free and overall survival after open radical cystectomy or robot-assisted radical cystectomy irrespective of urinary diversion...

PURPOSE OF REVIEW: Transurethral resection of bladder tumour (TURBT) followed by pathology investigation of the obtained specimens is the initial step in the management of urinary bladder cancer (UBC). By following the basic principles of oncological surgery, en-bloc resection of bladder tumour (ERBT) aims to overcome the limitations associated with conventional transurethral resection, and to improve the quality of pathological specimens for a better decision making. The current bulk of evidence provides controversial results regarding the superiority of one technique over the other...

PURPOSE OF REVIEW: Cytoreductive nephrectomy has had a variable role in the management of metastatic renal cell carcinoma (RCC) through the different systemic therapy eras. Initially felt to be beneficial with interferon, the utility of cytoreductive nephrectomy was called into question in the tyrosine kinase inhibitor (TKI) era. However, with the advent of immunotherapy for metastatic RCC, the role of cytoreductive nephrectomy continues to be debated. This study sought to evaluate the recent literature and discuss cytoreductive nephrectomy within the context of an improved systemic therapy era...

PURPOSE OF REVIEW: To review and summarize preclinical and clinical data on thulium fiber laser's (TFL) effectiveness (ablation rate, stone-free rate etc.) and safety in terms of laser injuries and thermal damage. This enables us to assess how the in-vitro evidence translates into the clinical real-life scenario. RECENT FINDINGS: In this analysis, a total of 21 preclinical trials have been included. Most of the trials use conventional Holmium:YAG laser as a comparator, with only a few assessing lasers with pulse modulation...

PURPOSE OF REVIEW: To summarize the latest findings and developments in genomics for kidney stone disease (KSD) that help to understand hereditary pathomechanisms, identify high risk stone formers, provide early treatment and prevent recurrent kidney stone formation. RECENT FINDINGS: Several gene loci associated to KSD have presently been discovered in large Genome-wide association studies. Monogenic causes are rare, but are thought to have higher penetrance, while polygenic causes are more frequent with less penetrance...

PURPOSE OF REVIEW: Local treatment in oligometastatic prostate cancer patients is associated with improved survival. Nevertheless, in term of surgery, cytoreductive radical prostatectomy has no level of evidence 1 and is an individual treatment approach. We reviewed the recent literature to highlight parameters for selecting patients for a surgical approach. RECENT FINDINGS: Retrospective data on oncologic outcome for cytoreductive prostatectomy are confirmed. We identified several parameters that help to select patients for surgery...

PURPOSE OF REVIEW: Transurethral resection of bladder cancer (TURBT) is in its standard form an inherently imperfect technique. Fluorescence-guided photodynamic diagnosis (PDD) represents one way to improve the outcome by enhancing tumour detection. Fluorescence has been used in connection with bladder cancer since the 1970s, with a number of studies being published since then. However, the method is still not recommended as a standard part of TURBT mainly because of the limited level of evidence of concerned studies, questionable cost-effectiveness and even contradictory results...

PURPOSE OF REVIEW: With advancements in surgical technology along with procedural techniques, this article throws light on the latest developments and applications of artificial intelligence (AI), extended reality, 3D (three-dimensional) printing and robotics in percutaneous nephrolithotomy (PCNL). RECENT FINDINGS: This review highlights the applications of AI in PCNL over the past 2 years. Mostly studies have been reported on development of machine learning (ML) based predicting models and identification of stone composition using deep learning convolutional neural network (DL-CNN)...

PURPOSE OF REVIEW: Salvage radical prostatectomy (sRP) is underutilized because of fear of historical high rates of peri-operative morbidities. However, there has been significant improvements in complication rates as well as oncologic outcomes in the recent years. RECENT FINDINGS: Complication rates have significantly declined for both open and robotic approach in the past decade. Rectal injury is now reported around 2%, which is down from 30% in the historic series...

PURPOSE OF REVIEW: To identify the latest advances on the utilization of suctioning devices in the surgical treatment of urinary stones. RECENT FINDINGS: Advances are being made to incorporate suction and pressure control capabilities in percutaneous and ureteroscopic lithotripsy. Multiple retrospective studies and few prospective studies have shown that suctioning with minimally invasive percutaneous nephrolithotomy, commonly referred to as Super MiniPerc, can lead to better stone-free rates (SFR) and shorter operative time with lower incidence of infectious complications...

PURPOSE OF REVIEW: Percutaneous nephrolithotomy (PCNL) constitutes the gold standard procedure for patients suffering from more than 2 cm renal stones. The puncture is a very critical step of PCNL, affecting manoeuvrability of the nephroscope, possibility to remove stone fragments, risk of bleeding and radiation exposure. The aim of the current review was to discuss the advances in percutaneous renal puncture. RECENT FINDINGS: Following technological evolution in medicine, there was a consistent development in the puncture techniques, aiming at the improvement of its efficacy and safety...

PURPOSE OF REVIEW: Currently, kidney-sparing surgeries are considered the preferred approach in low-risk tumours and in selected high-risk patients. Therefore, accurate diagnosis of UTUC is crucial for further management. The purpose of this review is to summarize available methods facilitating the diagnosis of upper tract urothelial carcinoma (UTUC). RECENT FINDINGS: Recent articles propose numerous techniques of UTUC diagnosis. In this review, imaging, as well as, urine-based and endoscopic methods have been described and assessed...
